"One trains in the power of faith, remaining in isolation, etc. Similarly, for the power of diligence, the power of mindfulness, the power of concentration, and the power of wisdom, one remains in isolation, one remains free from attachment, etc."

"The powers occur during the stages of warmth and summit on the path of joining. They are called powers since they control the phenomena of total purity (Wyl.rnam byang). Of course, the bodhisattvas on the path of accumulation have faith, diligence and so on, but they have not yet become powers. When the bodhisattva reaches the path of joining they become powers, but they are still susceptible to their opposing factors.
